Environment

Characters and living entities have a required Environment. These are a list of conditions that entity needs to live. If they are not fulfilled by a combination of the environment, dress, and inventory, the entity must make a save vs. Instadeath every combat round or turn. If they fail, they fall unconscious and lose 1d4 hitpoints per turn until they are in a complete environment.

Surface and Facility maps also have an environment. Their environmental qualities are listed for matching with entities, but map environments have a number of extra features as well.
